and State of Illi- Impro ements in Apparatiis for Making Cellulose,Vessels or Receptacles, of which the following is .a specification-.-

,-= f This invention relates to machines for making 'vesselsor receptacles from cellulose more or'less impure or other like material; and the object is. to provide a machine by means ofwhioh. a vessel or receptacle can be easily uickly formed and to provide a mold in whichpressure is exerted against the walls and bottom of the pail simultaneously.

, A further objectis to provide a machine inwhich the cellulose-pulp is fed into the top 5. .offithe mold and to provide a plunger which operates; Vertically and which will when p aced. in the mold form the innerwalls against which the said cellulose-pulp is pregsed .during the formation of the receptac e. A further object-fis'to so form the inner surface of. the segments which compress the pulp that the pulp will not adhere thereto formation said receptacles. p

, further object is to provide means on the plunger which willenablethe vessel or recepwhen the se ments are drawn away after the tacle'gto The released therefrom when said to is raised outof the mold.

An upper plate 29 is supported bythe standards 2, and 'intermediate'of the plate 29 is an opening 301 'Abase-plate 31 is also sup-- ported by the standards 2. One end of this 25 to clamps 43.

plate extends beyond the standards 2, form- I upon the upper end of cylinder 56, and a die ing a table 32. Intermediate of the baseplate 31 is an opening The mold into which the pulp is placed is 5 composed'of a series of segments 34 and staves 35. These segments and staves are disposed between the upper plate 29 and the base-plate 31. The inner surface of the stave 35 is knurled, as shown at 35*, and slightlv concave and is provided on each side thereof with flanges 36. The upper and lower portion of the stave is provided with extensions 37. These extensions are provided with the groove 38. Arib 39 is formed onthe r5 under surface of the upper plate 29 and a similar rib 40 ison the upper surface of the base-plate 31. Extensions 41 are formed on the upper and lower ends of the rear portion of the stave 35. hen said stave is placed in osition between the upper plate 29 and the ass-plate 31, the ribs 39 and 40 will engage -t.he grooves 38, formed in the extensions 37. One end of connecting-rod 42 is secured to projections 41 and the" opposite end thereof These clamps are secured to the upper and lower ends of the eccentric shaft 43 by means of screws or bolts 44.

The segment 34 is slightly concave, having its inner surface knurled at 34 and said seg- 'o ment is disposed between the upper plate 29 and the base-plate 31. This segment is adapted to rest against the flanges 36 of the stave-35, and is normally held in contact therewith by means of the spiral spring 45.

35-One end of this spring is secured to the bracket 46 and the opposite end thereof to :bar 47, which engages the rods 48. These -rods.-pass through op nings on the extensions 49 and are secured to the segment 34. There 40 area; lurality of the states and segments secure as previously described and disposed in'the manner as clearly shown in Fig. 3 of the drawings. A series of eccentric shafts 50. are j ournaled in the upper plate 29 and the base-plate 31. To that portion of shaft 50 which extends beneath base-plate 31 are rigidly secured pinions 51. These pinions are adapted to mesh with a gear-wheel 52. This gear-Wheel is held in operative position by 50 means of the collar 53, which is secured to the :under surface of base-plate 31 by the screws .or bolts 54.

An auxiliary frame is secured to the standards 2 in the lower portion of the frame A cylinder 56 is secured to the top plate' 57 The upper portion of said cylinder extends part way through the opening 33 in the baseplate 31. A gear-wheel 58 is rigidly secured to sleeve 56. This sleeve has screw-threads 6o in the lowerportion thereof, which engage the screw-threads on shaft 60. The lower end of shaft 60 is journaled in bearing-plate 60 and the opposite end extends through plate 57 and is provided with spider 61. A rim 62 is placed in the opening 33 and adapted to rest shaft is secured bevel-gear 78.

This die operates within the rim 62 and com )resses and forms the bottom of the receptacle. A yoke 64 is secured to; gear-wheel 52, to which is securedone end of connecting-rod 65. The opposite end of connecting-rod 65 is secured to wormgear 66. This worm-gear is secured to one end-of shaft 67, which is journaled in the frame 1 and the opposite end journaled in the table Torin-gear 66 is provided on one side with worm-teeth 68, which mesh with scrmv-threads on worm-shaft 69, mounted underneath the table 32. On one end of shaft 69 is secured a bevel-gear 70. This gear meshes with bevel-gear 71, secured to shaft 72, and said shaft is journaled in the bearings 73 on the frame 1. To the lower end of this shaft is secured a gear-wheel 74, which meshes witlran idler 75, journaled in the bearings 73, and the idler 75 meshes with gearwheel 58. To the upper end of shaft- 72 is secured beVel-gear76. A'shaft 77 is journaled in the frame 1, and to one end of this A bevel-gear 79 is also secured to this-shaft, which meshes with pinion SO. Said pinion' i-s secured on the lower end of shaft 81 and the shaft journaled in frame 1. A bevel-gear S2 is secured to the upper end of shaft 8]. A shaft 83is journaled in bearing-blocks 84, secured on the frame 1 This shaft carries the d living-pulleys 85 and 86 and bevel-gear 87. Said gear meshes with gear 82. A friction-clutch S8 is secured between the driving-pulleys 85 and 86, and 89 is a lever for operating said friction-clutch.

In Fig. 1' the plunger 4 is shown in 11- raised position and the parts in position to receive the cellulose-pulp,which is fed into the mold from the top. \Yhenthe pulp has,

been placed into said mold and it is desired to; I

form a pail, the friction-clutch 23' is placed in contact with driving-pulleys 28, which will cause the plunger 4, with its attachments, to move downward into the 1nold,and when the said plunger has moved dO\\'I1\\;:1ICl until the rim 8 rests upon the top of the upper plate 29 the friction clutch 23 maybe thrown out of engagement with the driving-pulleys 2S preferably by automatic means. The frictionclutch SS is then set in cngagement with driving-wl'iee l S5. This will operate the different shafts carrying gear-wheels and operate the eccentric shafts 5 0. These shafts are connected to the staves 35 The segments 34 being in engagement with said staves, the operation of the eccentric shafts will force the said staves and segments inwardly, thus compressin'g'the cellulose-pulp around the plunger 4. All the 'water or air which may be 111 the pulp will be forced through the perforations 4 into the hollow chamber of said plunger and removed by means of a pump connected to the hose or pipe 16. Snnultaneous with the movement of the gear which-forces the staves 35 and segments 34 inwardly will be operated, by means of the gear 7 4 on the shaft 72 the gear 8 This gear engages the 5 screw-threads on the shaft-60 and forces the'" preferably, by contact-levers for throwing the friction-clutch out of engagement with :5 the driving-wheel and into engagement with wheel 86. ThlS reverses the movement and draws the staves and segments away 'from,the recepltlacle compressed around the plunger 4. v enthe staves and segments and the forming-die drawn downward ,the friction-clutch 8:; may be thrown out of engagement with driving-wheels 85 and 86. f The friction-clutch 23 may then "be thrown in en 25 the hose 16 for pumping the Water out of the:

hollow plunger 4;, which isforced throu h the perforation 14 and into the plunger uring the formation of thereceptacle; -Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is'- v 1.
